' To all "whom it may "cov wcrn:

Be itfkn'own'that I, FRED S; ENGLIsH, a citizen ofthe United "Statesfand a resident of the city and county of New London, "State 5' oi 'Co'hnecticut, haveinventecl certain new "and useful Improvements in-EXtended-De- ""liveriesffor Printing- Presses, of which the following is a specification. Myinvention relates to a device for de livering"the printedsheetsr fromii; printing press or other-machine onto a table or sup port arranged beyond or extended froni-thc' printing press'proper.

In the"o rdinary" printing-"presses the sheets are delivered u'pon atablenrranged over part of the printing press mecha nisin and the pile table is generally" station- I :ary so that the first sheet delivered falls from the" 'delivery device 'upon' the table and 9 siico eeding sheets pile 'irpon the previoiisly deliveredsheet s, each succeeding sheet'falling a lesserflistahce and when the pile becomes too high for thedelivery device to 'propenydepmitthe sheets it is 'cus'tomary to remove the pile from-thepile' table by hand to makeroom for'si1oceeding sheets, "Where the table is"a'rrangediover part of 1tliepre'ss'the number of sheets Whichean be piled 'iipon it is very limited and if the sheetsere at-all'thick it is" necessary to remove the piles from the table often.- "The present device relates to tliaitfelass' of apparatuswherein thesheets are delivered he- 'yond' the o'rd-iirarylimits of the printing as press onto apile table which is movable and 'pon' which a largehumber of sheets-may hegiiled ne of the objects of my in'vent'io-n is to 1 proi ide an "extended" delivery device-Which 40may" be very' easily and very quickly attached to anordinary printing press.

Figure 3 is a plan view ot thei extended delivery device and of'the loivering'device. 'I haveshown the-side frame-115 of a tWo revolution, fiat he'd printing press andthe impression cylinder 116. The delivery device is adapted to takethesheets singly as they come from ,this' impression ,cyl(inder and to deliver them iiponthe pile table ar "ranged beyond or in front of. the'press. "At 1 I have shown the ordinary carriage of a printed side up delivery deviceand'thiscan riage has WllQBlSl 2 amhe rearend *endsimilar WllQGl'S?) at theforivarchend i't h'ieh run on tracks 4 at eaclrside of 'tlie"press.

Iii former practice'these tapes peeled or tiirned away 'u'nder the sheet upon the rear- Ward motion of the carriage and let the sheet fall iipon a pile'ta'ble' arranged over the inking device. But in the present case "these'tapes deliverthe-sheet "upon another set of tapes which carrythe sheets to the extended piletable'; as will appear. Above the tapes 18 there are other tapes 6, which are endlessandrtravel overt-he rea'r r'o-llers 6 and over forward'*rollersfit; the tapes 6 being inclined; so that their lower runs converge tovvardthetapes 1'8 and'impinge upon the roller'5 at the forward end of thecarriageu The sheets carried bythe tapes 18 are engaged on their top surface bythe tapes 6" (which are generally in the form of round belts) aiid'the latter cooperate to pre- "vent the sheets from flying oiithetape belts 18"%ii1(l assist in cerrying'the sheet-s forward.

tracks 4: lisually extend only tothe 11 forward end of the press proper and in the present structure I have arranged supplemental or extension tracks and I have pro vided an extension on the delivery carriage which travels on these extended tracks.

The carriage extension consists of bars 7 which are secur'edat one end to the bars 1 by means-of thev plates 20. The COIlllQC' tion between the bars 7 and 1 is a pivotal one so that the forward part or extension of the carriage may pivot vertically in relation to the rearward part in order that the de- Vice may operate smoothly regardless of whether the track extensions are parallel I withthe tracks-ft. On t-he bars 7- there is mounted an idle roller 8 which corresponds with the roller 0. Certain of the endless tapes on the carriage marked 18, engage around the roller 5 for the purpose of carrying the sheets up to this roller,- whereas 1 other endless tapes 19, which lie parallel with the tapes 18, and preferably alternate side by side with the latter, pass around the roller 8, with their upper and lower runs straddling the roller 5. Except for their engagement with theroller 8 instead of the roller 5 these tapes are connected with the same parts and are operated the same as the tapes 18. As the tapes 18 and their opera- 'tion are well known in the artand are desori'bediin said'Fenner patent, a more complete description thereof is unnecessary here.

The extension bars 7 also carry rollers 9 corresponding with the rollers 6 and there are forward rollers 9 corresponding with the roller 6 Endless belts 9 engage over these rollers 9", 9 and they converge toward the tapes 19. These belt-s. serve to keep the sheets from flying off the tape belts 19 and assist in carrying the sheet forward. The rollers 9" on which the belts 9 engage are mounted upon the shaft 12 and the latter is operated from the roller 8 by means of a crossed belt 15 engaging over the pulleys 14 and 13 arranged respectively on the shaft 12 and roller The rollers 10 travel on the track'rails 11.

These latter are bolted at one end to the pile table frame at one point by the bolts 21 and at the opposite end they are bolted to the forward ends of the track rails 4 by bolts 22; The track rails 11 may be in the same plane as the rails 4 or they may incline upwardly or downwardly therefrom. the connections permitting of this. Thetracks 11 do not hav'e'to be aligned with the tracks 4 and the attachment of the extended delivery to the press is made very easily. As the forward extension of the delivery carriage, i. e.

the bars 7, are pivotally connected to the bars 1, the part of the carriage which travels on the tracks 11 will operate even if the latter are not aligned horizontally with the tracks'4.

As the sheet comes out from the impression cylinder 116 the carriage is moving forwardly or away from the cylinder, starting at about the time the head of the sheet leaves the cylinder; and when the carriage gets to the end of its forward stroke the sheet will have been carried forward so that its rear end lies a short distance ahead of the cylinder and the sheet will lie on the tapes l8. lVhen the carriage moves back again toward the cylinder the sheet remains stationary during this movement of the carriage and the sheet will be in the bight of the tapes 6 and the roller 5.

As the carriage starts forward on its second cycle another sheet starts out from the cylinder upon the carriage tapes 18; and the first sheet is carried forward with the carriage, being held at its leading edge in the bight of the tapes 6 and the roller 5 until the carriage reaches the end of its forward stroke when the first sheet will be about over the ink fountain. back again toward the cylinder the tapes (3 and roller 5 move back in relation to the sheet, leaving the latter in its advanced position. hen the carriage is back near the cylinder it will have completed two cycles and there will then be a sheet resting on the tapes 18 not far ahead of the cylinder and a sheet ahead of it, resting on the tapes 19 with its leading edge in the bight of the tapes 9 and roller 8. e

The carriage will now start forward on its third stroke and the first sheet will be carried out over the pile table by the tapes 19. As the carriage starts backward again the tapes 9 and roller 8 run back over the sheet and this sheet falls on the pile table. The same action takes place with each successive sheet.

The pile table may be very simple in construction. I have shown a pair of forward legs or supports consisting of bottom plates or feet 23 adapted to be bolted to the floor or foundation on which the press is mounted; of the uprights 24, and the castings 25 mounted on the tops thereof.

The rear legs consist of the base castings 26 which rest on the floor or foundation near the press, of the upright posts 27, and the top castings 28. The legs are connected back and front by the side channel irons 29 and 30 and they are tied crosswise by the tie rods 113 and 114. The pile table .31 on which the sheets are piled, is supported upon T irons 32, extending across and underneath the table and these T irons have hooked ends which engage the ordinary shackles 33. There is a pair of these shackles at each side of the pile table and they are carried upon the lower ends of the cables 31" which extend upwardly to the top of the pile table and pass partly over the forward and rearward sheaves 34, 35, at opposite sides of the table frame. From the sheaves 34, 35, the

vllli i lcables pass over the sheaves-36, to the wind ingi drums 37, fixed tort-he opposite ends of a shaft 38.

Thetable Sir-starts to'rcceive sheets-from. thedelivery carriage when the-table is in its raised positionoa11(l.-tl1e :table 1s 1 lowered gradually or step bywstep :w-ith-the cables 31 until the required amount of sheets have beendpiled upon it or until the table has reached its lowermost position, and a truck may be run under the table, receive the descending table and pile upon it, whereupon the shackles 33 can be unhooked from the T irons 32. The entire table and pile may be moved away upon the truck and there is room for the truck to be removed at the sides or the front of the table frame. 32 may be replaced in the shackles, another table placed thereon, and the table raised to the uppermost position to receive another pile. The pile table, it will be noted, is placed to the front of and beyond the press and it has a vertical movement from approximately the height of the delivery carriage nearly to the floor so that it is adapted to receive a much larger pile than if the table were on some part of the press.

The operation of the device has been set forth in the above description. As the car riage reciprocates periodically and in time with the. operation of the press the sheets are received singly upon the carriage tapes and they are advanced in three successive stages upon the carriage until they reach their final position on the tapes above the piling table. hen a sheet reaches this position it is deposited at the next rearward movement of the carriage upon the pile table or upon the topmost sheets of the pile. No additional mechanism is required other than the extension of the carriage and the additional tapes, in order to carry the sheets beyond the press to the extended pile table, so that the device is very simple. As the extended portion of the carriage travels over the extension rails and since the carriage extension can articulate, it is not necessary that the extension part of the delivery align perfectly with the: remainder of the delivery. As the sheets are deposited upon the top of the pile they are jogged from all four sides to make the pile eve-n.

Having described my invention, what I claim is:

1. The combination with a printing press and a delivery table arranged beyond the press, a delivery carriage on the press adapted to convey the printed sheets from the im pression cylinder, and an extension on said delivery carriage adapted to receive the sheets from the delivery carriage said extension being adapted to reciprocate and to move to a position )ver said delivery table.
